VOX AC30CC2 Normal Channel won't work by itself
hi can anyone tell me if my AC30CC2 is faulty or if this is just how it is:
If I plug into the normal channel I get no sound at all unless I turn the input link toggle off,

The manual suggests that would then mean I am just playing the "normal" channel by itself (without any input from the Tone Boost channel)
But I notice that if I adjust EQ or volume on the Tone Boost controls, it still flavours the sound.

So in other words I have no way of playing the Normal Channel purely by itself.
And depending on what position the Input Link toggle is on, I get no sound at all.

The Tone Boost channel seems to work OK.
But I really would like to know if the Normal channel is designed like this, or if my amp is faulty?

Turn down the TB Volume control.

Does the EQ still affect the Normal channel? (it shouldn't)

that does seem to work.
But that sounds like it shouldn't be happening at all though right? e.g. that suggests there is no such thing as Normal by itself?

And is it correct that the toggle switch acts as a killswitch, e.g. no sound at all if it toggles one way?... or is that just my amp not wired right?

The 'Link' switch will give you the Normal channel (or not) along with the TB channel only when you are plugged into the TB input.

When in the Normal input, if you toggle the link to link, you will get nothing.

Here is the SM.
The block diagram is on page 5.

Thanks Jazz,
I can't read diagrams sadly but thanks for your efforts in finding that!
When you say:
"The 'Link' switch will give you the Normal channel (or not) along with the TB channel only when you are plugged into the TB input."
That would suggest to me that mine is odd, as when plugged ONLY into the NORMAL channel, I am also getting sounds from the TONE BYPASS channel?

First off, my answer was to your question about no sound when the link switch is thrown.

"That would suggest to me that mine is odd, as when plugged ONLY into the NORMAL channel, I am also getting sounds from the TONE BYPASS channel? "
This part is why I asked you to turn down the TB volume.

The Normal & the TB both share the first tube cathode resistor.
I can only assume that there is a coupling affect from TB to Normal because of the circuit design.

OK cool thanks for that Jazz
